From what I remember - and obligatory spoiler alert since, caffeinated hamster as I am, I'll be spilling the beans-- ugh, that's too many coffee puns in as many seconds...
The Enterprise finds a near-parallel-Earth-development, which had made it into the equivalent of 1930s Earth. That's when the previous starship arrived and the captain of that ship beamed down and told the natives of the Nazis for whatever reason, with Kirk and crew trying to undo the damage done. Right down to a very tidy ending just waiting to find a rug to be swept under.
In reality, it's a bottle show that uses costumes, sets, and props from "Hogan's Heroes" in order to save money.
The laser cutting scene didn't impress the child version of me a few decades ago. The adult child I am nowadays doesn't believe it either. Other references come to mind...
Still, the episode isn't without certain charms. There were some good quips and exchanges. Like this one:
"
Captain, I'm beginning to understand why you earth men enjoy gambling. No matter how carefully one computes the odds of success, there is still a certain... exhilaration in the risk."
"
Very good, Spock. We may make a Human of you yet."
"
I hope not."
"Do you know what we do to responsible Zeons?"
If you want to punish them, you make them watch this episode,
LOL!!
which I generously gave a 5. The downhill slide of episode quality accelerated with this one. By the time this turkey hit the TV screens of America, all-time classic second season episodes like "Amok Time," "Who Mourns for Adonais," "The Doomsday Machine," "Journey To Babel," and "Mirror, Mirror" must have seemed like they were produced years, not months, before.
Why does this episode bother me? Let me count the ways....
1. Nazi's. What kind of historians uses that example of "efficiency" to "unify" a "fragmented" planet? (maybe new Trek will reinvent this episode and choose ISIS as their "unifying force").
Technically, they were efficient. John Gill (absolutely no relation to the musician who was born in 1966) didn't do a good enough job at explaining the nuances, I could imagine the meeting going something like this:
Gill: "A unified country is good for all the people but don't do what the nazis did"
Melakon: "What did they do"
Gill: "Well, they did all these atrocities... (long list of atrocities adumbrated,
which perked up Melakon's interest) ...So when getting your society back together, be sure to rub people the right way ♫"
Melakon: "Will do." (syringes Gill with the brainadope)
2. Swastikas. See #1. Also, couldn't they come up with an alternative logo for these fools?
The alien lizards from "V" did a better job... why not these guys?
3. Zeon for Zion. Talk about hitting the audience over the head with a 10 pound sausage.
Pretty much, it readily proves how this story was by far the weakest parallel Earth escapade.
4. The Nazi with the crisp British accent. How BBC of the producers.
LOL.
At least he wasn't Colonel Clank. The episode could have been worse if they tried another laugh-fest due to the success of "Tribbles".
Wasn't this episode in the latter half of season 2, past the point when the show was originally axed (prior to the fan mail barrage that got it renewed and sent to the Friday timeslot?)
5. The "let's just forget the impending genocide and all be friends" ending. "Now we'll start to live the way the Fuhrer meant us to live." That may be the most insane (or inane?) line of dialog spoken in the entire series! The fuhrer was the guy who made you Nazis, BritNazi!
Better than Reverend Wainright from the 1989 Doctor Who story "The Curse of Fenric", who was a Nazi sympathizer.
It's definitely a glib ending, making endings like "The Cloud Minders" seem nuanced and intricate by comparison.
I'm sure I can think of more things, but you probably get it by now.
Like "Return To Tomorrow," this episode bears more resemblance to a third season episode than a second season affair. I'm just as excited as watching snoozefests like "The Empath," "Let That Be Your Last Battlefield" or "For The World Is Hollow And I have Touched The Sky" as I am as watching this nonsense.
Ugh, "Return to Tomorrow". Kirk had a great monologue in one scene, but the rest of the story was... sub-season 3 as well as this one.
"Battlefield" has some good acting despite very glib overgeneralizations. "Empath" is just a hollow, empty episode. FTWIH&IHTTS pretty much fell apart the moment-- wait, the title alone has the story falling apart during reading the first 40% of syllables, never mind shortly after the commercial break when Kirk breaks his promise to McCoy to not blab about his medical condition in the pre-credits bit and puts into his log informing Starfleet how McCoy's gonna die and an immediate replacement needs to be sent out, stat. Never mind the convenient ending, "Oh look there's a cure! Hey Starfleet, nix my request and don't let McCoy know I squealed."
Final thought: Thank goodness the SS Horizon didn't leave a book on Nazi Germany behind!
Not "Bonnie and Clyde" world with the Fizzbin! (yikes...)
In premise, the parallel Earth development was novel, while being money-saving and - yeah - it's not inconceivable that dominant species would be virtually human in appearance, not merely
humanoid. It worked better for stories like "Miri", but TV shows like "Sliders" used the concept a lot more effectively. Trek overused the trope a few too many times as well, leading to gangsterworld and naziland...
